- public class DHKeyFactory
- extends java.security.KeyFactorySpi
This class is used to convert Diffie-Hellman keys into a format
usable by the ABA provider. Currently this class can only convert
from a KeySpec into a Key. The supported KeySpec classes are
DHPublicKeySpec and DHPrivateKeySpec.
Not currently finished.
This class should not be instantiated directly, instead use the
java.security.KeyFactory interface.

DHKeyFactory
public DHKeyFactory()
engineGeneratePrivate
protected java.security.PrivateKey engineGeneratePrivate(java.security.spec.KeySpec keySpec)
throws java.security.spec.InvalidKeySpecException
- Generates a Diffie-Hellman PrivateKey object from the provided key
specification (key material). This class supports the
DHPrivateKeySpec KeySpec class.
- Overrides:
- engineGeneratePrivate in class java.security.KeyFactorySpi
- Throws:
- java.security.spec.InvalidKeySpecException - The provided KeySpec was not
a DHPrivateKeySpec KeySpec.
engineGeneratePublic
protected java.security.PublicKey engineGeneratePublic(java.security.spec.KeySpec keySpec)
throws java.security.spec.InvalidKeySpecException
- Generates a Diffie-Hellman PublicKey object from the provided key
specification (key material). This class supports the
DHPublicKeySpec KeySpec class.
- Overrides:
- engineGeneratePublic in class java.security.KeyFactorySpi
- Throws:
- java.security.spec.InvalidKeySpecException - The provided KeySpec was not
a DHPublicKeySpec KeySpec.
engineGetKeySpec
protected java.security.spec.KeySpec engineGetKeySpec(java.security.Key key,
java.lang.Class spec)
throws java.security.spec.InvalidKeySpecException
- Returns a specification (key material) of the given key object in
the requested format.
Currently supports standard DH keys, DHPublicKeySpec and
DHPrivateKeySpec KeySpec classes.
- Overrides:
- engineGetKeySpec in class java.security.KeyFactorySpi
- Parameters:
key - the keykeySpec - the requested format in which the key material shall
be returned- Throws:
- java.security.spec.InvalidKeySpecException - if the requested key
specification is inappropriate for the given key, or the given
key cannot be dealt with (e.g., the given key has an
unrecognised format).
engineTranslateKey
protected java.security.Key engineTranslateKey(java.security.Key key)
throws java.security.InvalidKeyException
- Translates a Diffie-Hellman key object, whose provider may be
unknown or potentially untrusted, into a corresponding key
object of this key factory.
- Overrides:
- engineTranslateKey in class java.security.KeyFactorySpi
- Parameters:
key - - the key whose provider is unknown or untrusted- Throws:
- java.security.InvalidKeyException - if the given key cannot be processed
by this key factory.
